We did just that and we took off the resinator and we had to hollow the cat out due to the fact that the mechanic lied to me about them doing it. But after all that guess what the same problem. Them i had a great idea check the Fuel filter and guess what. It was the orignal one 144thousand on it. Changed it problem fixed and the stalling out problem a loose battery cable. All good to go now. It still dose not wine when you get on it but it halls like a 3800 should. Any thougths on the super charged not wining or pulling like it should.
